I agree that returning the element is similar to what List does, but arrays
are not lists ;)  I would argue that something like find_index is all that'=
s
necessary, and you can do a lookup if you need the element.

Actually, I agree it makes complete sense for partition.  As I think about
it, I think filter and find_all should be different.  find_all should retur=
n
a list, and filter should return an array.  And possibly, filter should be
defined in terms of find_all.
